To reduce space requirements, vibrations and certain stresses in an engine, a different one of two pistons is mounted on each end of a single piston rod to which the crankshaft is attached by a cylindrical shaped connector that orbits around the crankpin while rotating inside the piston rod. The crank interfaces directly with the piston rod through gear portions or a cam-cam follower through the center of each stroke. To reduce vibrations and certain stresses in an engine, a different one of two pistons is mounted on each end of a single piston rod to which the crankshaft is attached by two arms extending orthogonally from its central portion, each arm being mounted to a different one of two different connecting rods. To balance inertia forces, two oppositely rotating crankshafts are counter-weighted to balance the inertia forces of the assembly in its axis of oscillation and to balance each other outside that axis of motion, or two piston assemblies oscillate opposingly in the same axis eliminating the need for the crankshafts to balance their inertia forces.
